A technique for executing a segmented virtual machine (VM) is disclosed. A plurality of core VMs is implemented in a plurality of core spaces. Each core VM is associated with one of a plurality of shell VMs. Resources of the core spaces are allocated among the core VMs.

Resource allocation

Stitching a proxied connection between a first core virtual machine (VM) and a second core VM is disclosed. Stitching includes determining that a stitched connection should be generated between the first core VM and the second core VM and generating the stitched connection between the first core VM and the second core VM.

Source switching of virtual machines

A technique is disclosed for redirecting information in a segmented virtual machine. The technique includes sending information to a shell VM and redirecting the information to bypass the shell VM. A technique for evaluating whether to redirect information may include sending a discovery packet, receiving a reply to the discovery packet; and determining whether a switch is capable of stitching based on the reply. A technique for responding to a discovery packet may include receiving the discovery packet at a switch and sending a response indicating a capability of the switch.

Information redirection

A technique for executing a segmented virtual machine (VM) is disclosed. A plurality of core VM's are implemented in a common core space. Each core VM is associated with a shell VM. Resources of the core space are allocated among the core VM's. A core VM is associated with a shell VM configured to perform shell VM functions and communicate with the core VM. VM internal execution functionality is performed on the core VM. The shell VM may be bypassed to communicate with an external application.

System and method for allocating resources of a core space among a plurality of core virtual machines

A system and method are disclosed for a segmented virtual machine. The segmented virtual machine includes a core VM and a shell VM associated with the core VM. The core VM is configured to perform VM internal execution functionality and the shell VM is configured to perform shell VM functions and communicate with the core VM.

Segmented virtual machine

An internet service node (ISN) enabling the provision of desired service policies to each subscriber. The desired service policies for each subscriber are provided as an input. The desired service policies are translated into processing rules. Each processing rule contains a classifier and associated action. A classifier generally identifies the application data flows to which the action may be applied to provide the desired service policies. The processing rules may be generated dynamically to implement the specified service policies for each subscriber. Each data bit group may be classified to associate with a subscriber and only the processing rules corresponding to the subscriber may be applied to the data bit group to provide the desired services.

System and method for providing desired service policies to subscribers accessing the internet

An internet service node (ISN) enabling the provision of desired service policies to each subscriber. The ISN may contain multiple processor groups, with each subscriber being assigned to a processor group. The assigned processor group may be configured with the processing rules, which provide the service policies desired, by a subscriber. A port may determine the specific processor group to which received data is to be forwarded. A content addressable memory with masks for individual locations may be implemented to quickly determines the processor group to which received data is to be assigned to. Due to the features of the present invention, an ISN may be able to serve a large number of subscribers efficiently. The ISN may be used at the edge of an access network.

Providing desired service policies to subscribers accessing internet

In one embodiment of the invention, browser plug-in includes a personal content tunnel (PCT) object processor, a PCT resolution module, and a server interface. The PCT object processor processes a PCT object returned by a content server in response to a request from a client. The PCT object contains PCT information. The PCT resolution module resolves a service uniform resource identifier (URI) using the PCT information according to a PCT resolution protocol. The service URI identifies a PCT resolution server. The server interface receives a content URI and a PCT termination point resolved by the PCT resolution server.

Broadband content delivery via personal content tunnel

An internet service node (ISN) for sending unsolicited web pages only to users agreeing to receive unsolicited web page. An internet service provider (ISP) may charge lower rates to users agreeing to receive unsolicited web pages. For example, an ISP may send an unsolicited web page in response to the first web page request for a user. In general, a user may agree to receive different types of unsolicited web pages under different conditions. An ISN may monitor the data flows related to the user to determine whether any condition is satisfied; and a web server may be used to generate and send the corresponding unsolicited web page.

Flexible external control of unsolicited web pages sent to a user accessing the internet

An operating environment for use on a computer system to provide operating system services to a user application running on the computer system. The computer system includes a network connecting the computer system to at least one other computer system. The user application generates operating system commands requiring access to the network, and commands requiring operating system actions that do not access the network. An operating environment according to the present invention includes a network server for accessing the network, a non-network server for executing operating system commands not requiring network services, and an emulation library for receiving the operating system commands generated by the user application. The emulation library decodes each of the received operating system commands to determine if that command requires network services, and forwards a command based on that received command to the non-network server or the network server depending on whether or not that command requires network services. The emulation library shares the same task as the user application and acts as a proxy for the operating system. The network server includes the translation routines for translating operating system commands to commands for one or more network protocol stacks.

Network operating system adapted for simultaneous use by different operating systems

A functional verification system suited for verifying the function of cycle based integrated circuits (IC) design. The IC design is divided into a plurality of combinatorial blocks connecting sequential elements. Truth tables corresponding to the divided blocks are computed and stored in a memory. The output values of the IC design are determined by evaluating the blocks. The evaluation typically entails one memory access as the truth tables are pre-computed and stored in a memory storage. Accordingly the output values are computed quickly. The storage is implemented using random access memories and a XCON is designed to ensure the dependencies are preserved during the evaluations.
